What Does a Private Investigator Do?
Private investigators (PIs) in Australia are licensed professionals hired by law firms, insurance companies, corporations, and private individuals to uncover facts, gather evidence, and locate missing persons or assets. The industry is highly regulated, requiring strict adherence to privacy laws, surveillance legislation, and state-based licensing acts.
Common investigative services include:
- Factual Investigations: Interviewing witnesses, taking statements, and gathering documentary evidence for insurance claims, workplace incidents, or legal disputes.
- Surveillance: Covertly observing and recording a subject's activities, often used in workers' compensation claims, corporate fraud, or family law matters.
- Skip Tracing & Location Services: Finding individuals who have absconded from debt, witnesses required for court, or missing family members.
- OSINT & Cyber Investigations: Gathering intelligence from open sources, social media, and public databases to build profiles or trace digital footprints.
- Background Checks: Verifying credentials, employment history, and conducting due diligence for corporate clients.
The Legal Framework: What PIs Can and Cannot Do
A common misconception is that private investigators have special police powers. In Australia, PIs are civilians and must operate within the same legal boundaries as any other citizen, albeit with specific exemptions under certain privacy and surveillance laws when acting in a professional capacity.
Important: Private investigators cannot tap phones, hack into private emails or social media accounts, access restricted police or government databases, trespass on private property, or make arrests.
Key Legislation
- Privacy Act 1988 (Cth): Governs how personal information is collected, used, and stored. PIs must ensure their data collection is lawful, fair, and not unreasonably intrusive.
- Surveillance Devices Acts: Each state has its own act governing the use of listening devices, optical surveillance (cameras), and tracking devices (GPS). Generally, recording a private conversation without consent is illegal, and placing a GPS tracker on a vehicle without the owner's consent is strictly prohibited.
- Trespass Laws: PIs cannot enter private property without permission to conduct surveillance or gather evidence. Observations must be made from public property or areas where the PI has a lawful right to be.
State-by-State Licensing Requirements
To operate legally as a private investigator in Australia, you must hold the appropriate licence for the state or territory in which you are conducting the investigation. The foundational requirement across most jurisdictions is the completion of the Certificate III in Investigative Services (CPP30619).

How to Build a Successful PI Practice
Getting licensed is only the first step. Building a sustainable investigative business requires the right tools, continuous training, and a strong professional network.
1. Join an Industry Association
Clients, especially law firms and insurance companies, look for investigators who are members of recognized professional bodies. AIMPAC (Association for Investigators, Mercantile Professionals and Compliance) is Australia's leading association. Membership provides you with a unified voice, a professional directory listing, and access to free CPD (Continuing Professional Development) courses.
2. Equip Yourself with the Right Tools
Modern investigations rely heavily on data and open-source intelligence. Platforms like TracerDesk provide licensed professionals with access to comprehensive search databases covering Australia and New Zealand, as well as advanced OSINT tools like TraceLink (relationship mapping) and SocialScan.
3. Continuous Professional Development (CPD)
The investigative landscape, particularly regarding cyber investigations and privacy law, changes rapidly. Elite training providers like ThinkEdu offer advanced courses such as the OSCI (Open Source Collection & Intelligence) program, which teaches modern tradecraft for finding, collecting, and preserving digital evidence.
4. Insurance and Compliance
If you are operating your own agency, you must hold adequate Professional Indemnity and Public Liability insurance. You must also ensure your business complies with the Privacy Act, including having a clear privacy policy and secure data storage protocols.
